California Grade Direct-Fit Converter
MagnaFlow 5582740 is a California Grade CARB-compliant direct-fit catalytic converter with an integrated exhaust manifold for front-position applications. It is built for a bolt-on installation on listed Honda and Acura vehicles, using stainless steel construction, a ceramic substrate, and OE-style spun body design to match factory fit and function.
This MagnaFlow California Converters part is engineered for drivers who need a direct replacement that aligns with California Air Resources Board requirements on the listed vehicles. The compact, low-mass design supports thermal efficiency, while the single laser fusion weld helps reduce leak points. MagnaFlow also uses 3D scanning during development to verify fitment against original equipment geometry.
